Abstract：The Xijiang Wuzhou Section Aquatic Germplasm Reserve is a key zone for aquatic biodiversity conservation in the Pearl River Basin. Monitoring data indicate stable water quality（Class II-III ），withapH range of 7.1～8.08 and dissolved oxygen（DO） levels of 6.12～9.49mg/L . Petroleum and phenolic pollutants have shown a consistent declining trend. A total of 59 fish species （including 5 endangered species） have been documented. The primary environmental stressors include seasonal water quality fluctuations，habitat fragmentation due to hydraulic engineering，and sporadic ilegal fishing.Based on comprehensive monitoring findings，it is recommended to：Strengthen the monitoring network and zonal management;Strictlycontrol anthropogenic disturbances，and achieve a balance between conservation and sustainable development，thereby serving as a model for aquatic germplasm resource protection in the Pearl River Basin.
